The synthesis of highly extended and sulfur rich tetrathiafulvalene de
rivatives, designed to avoid any internal cyclisation during their sub
sequent electrooxidation, is described Their pi-donating ability is co
nfirmed by cyclic voltammetry, as well as the good stability of each o
f their oxidized species (up to an hexacationic state in one case). (C
